Hi,
I’m trying to enable hard float computation on arm.
I think I have managed to enable it doing the following changes:
1) Set a new environment var ANDROID_ARCH_TARGET=armeabi-v7a-hard
2) Adding
equals(ANDROID_TARGET_ARCH, armeabi-v7a-hard): \
QMAKE_CFLAGS = -Wno-psabi -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16
-mhard-float -ffunction-sections -funwind-tables -fstack-protector
-fno-short-enums -DANDROID -D_NDK_MATH_NO_SOFTFP=1 -Wa,--noexecstack
-fno-builtin-memmove
3) QMAKE_LFLAGS = --sysroot=$$ANDROID_PLATFORM_ROOT_PATH
-Wl,--no-warn-mismatch -lm_hard
4) QMAKE_LIBS_PRIVATE = -lgnustl_shared -llog -lz -lm_hard -ldl -lc -lgcc
Code compiled and ruined fine but couldn’t notice a faster performance (I have
profiling timers in critical parts of the application).
Has anyone done this before?
Regards,
